In depth question about text boxes? Help please! (flash MX)

Hey all,
Im fairly new to the forums, but have been on the site quite a while,
hope someone can help.
I want to create a space, that people can write in, i guess you would use input text, But, i want it to have a save and load feature, and also, how would you put in a button that cleared all text from the box, how would you make an exit button, how and lastly how would you make a change of font button.
I know that people will probably get angry with me, but i hope someone can help.
Thanks,
Ben
